Experimental Study of the Influence of Impact Mass on Damping Performance of Impact Dampers

Abstract:

We present a simulating experimental method used for studying the influence of impact mass on damping performance of impact dampers. The free mass in the impact damper had equal total mass but different size individual. We tested the damping effect of the damper under the same external force separately. The main results obtained in the experiments indicated that the impact damper had a good damping effect in the resonance region of the main system. The mass value of the free mass participating in vibro-impact was variable. In addition, the damping of the main system was related to the size of the free mass. In the conditions of equal total mass and same material, the size of the free mass was smaller, the effect of the vibration control was better.
